Paris-exclusive: French police have arrested two female suspects after an argument about dogs allegedlydescended into violence and racist insults including the words 'Dirty Arabs'.

One of the Muslim women said the attackers had pulled out a knife after refusing to put their dogs on a leash and slashed her on the skull, arm and ribs.

Those in custody are described as being white women of 'European appearance', who now face 'attempted murder' charges, said city prosecutors.

The attack follows the gruesome killing of 47-year-old teacher Samuel Paty last Friday by a refugee Islamist terrorist after cartoons lampooning the Prophet Mohammed were shown to a secondary school class on freedom of speech lesson.
